At GAS FIX we provide power flushing methodically and thoroughly, pipe by pipe, radiator by radiator, including the boiler. Once your whole system has been power flushed thoroughly, we will refill it with clean water, and a corrosive inhibitor will be added to your central heating system. This will be clearly labelled as containing this chemical substance. Power flushing usually takes from 4 hours to a day to complete, it all depends on the size, number of radiators and the type of system you have.
The success of a power flush will depend on the level of heating system corrosion which has occurred beforehand. The process will cure most circulation problems.
You should really request power flush when:
You feel cold spots on the radiators.
Blocked radiators.
Radiators frequently needing bleeding.
Radiators slow to heat up.
Noise from the boiler.
Poor or no hot water.
Boiler failures.
Heating circulation problems.
